The journey begins

I've been watching MSNBC and its coverage of the people coming out to greet President-elect Obama on his train journey from Philadelphia to Washington. The crowds – especially in Baltimore – are huge, and folks are truly in a celebratory mood.Obama and VP-elect Joe Biden seem to be taking it all in. It is a vivid reminder of the deep well of goodwill and support they will enjoy as they chart their political course. NBC's Chuck Todd is on board that train and will check in with us, as we kick off our inauguration coverage on Nightly News this evening.
